This is the Vandervell A+ center tang main bearing in premium VP2 lead-copper material. Note that the lower halves of these bearing shells have no oil channel, but this is how the engines were originally supplied by Rover and are correct for this application. Normally stocked in STD/010/020 sizes. If the oil channel is desired, order VPM91120 bearing, but you will have to modify the main caps for the offset tang.
PACKAGING NOTE: Product may be packaged in any of the box styles shown, but please be assured that the product is identical.
